Currently Playing: Vintage electrical tech - Weston Sensitrol Relay

This vintage electrical meter is incredibly sensitive, and latches relay contacts with just 18 nanowatts! Link to old Weston advertisement from 1950's: https://pdfs.semanticscholar.org/7efe/c1a814298b121ecf67947183d3630db7f3b0.pdf https://www.patreon.com/AppliedScience
